CAMBELL SL300701AV Timed Electric Automatic Drain Valve

The SL300701AV is a 1/4" NPT timed electric condensate drain valve designed to automatically purge water from compressor tanks when powered by 110 V AC. Campbell Hausfeld equivalent CE300200AV, it accepts 1/4" NPT fittings on both inlet and outlet and includes a built-in ball valve and Y-strainer to catch debris. It operates on adjustable open/close cycles—typically 0.5 to 10 seconds open and 0.5 seconds to 45 minutes off—and supports up to 230 PSI. A 4 mm diameter precision orifice controls the condensate discharge, and the unit provides LED indicators plus a test button for quick status checks. The assembly comes with a 6 ft power cord with plug and weighs about 2 lb. This timed drain is suited for automatic condensate drainage on air compressor tanks and similar receivers, helping remove water and contaminants without manual intervention.
